Systems and methods are provided for controlling a purging operation of a fuel vapor canister in a boosted engine. One method comprises purging stored fuel vapors from the fuel vapor canister to an inlet of the compressor via an ejector while bypassing a canister purge valve, the ejector being fluidically coupled to the fuel vapor canister by a distinct passage coupled upstream of the canister purge valve, where motive flow through the ejector may be regulated by a shut-off valve. The shut-off valve may be adjusted based on whether or not the engine is boosted.
